The Dark Magician Transmigrates After 66666 Years66666년 만에 환생한 흑마법사

Arrogant. Typical dude that lets power get into his head. Read if you want.

With or without a harem tag novels like this ALWAYS has harem

It does have a harem not the common one though, but, it's there. He doesn't act like a dark magician, he doesn't act like a anti hero either. He's a hypocrite he kills the dark magicians who were practicing curse magic because according to him it's not a "good" reason to experiment on people with curses just for power although in his prime he killed millions to obtain his power and experimented with thousands this ticks me off

Shame this a harem, i avoid that tag like a plague.

so far 70+ chapter is a 6-year old kid fighting way above his league , struggling and plot-armor helping him at every moment
seriously he should just hide and focus on getting stronger

Think it needs 1 more 6. So that it will be 6x6 not 5x6

Demon abandoned all emotions in his past life because he thought they were a burden gets reincarnated and starts to feel familial love, and it has 4.2 on NU
